IR manifold design

[TVS]

> Accepted wisdom for 4 pot IR is that at these low RPMs the injectors
should be downstream of the butterflies. Upstream only becomes an advantage
at 5000+. But like all accepted wisdom is usually based on the fact the IR
TB's have their injector pockets in this location:-)

> The higher the injector, the bigger the accel squirt needed, so possibly
part throttle drivability may decrease, BUT you get better atomisation at
WOT. Oh and potentially worse emmissions.

I would have expected that atomisation would also be good at part throttle
as the extreamly high air speed past the butterflies would help to brake up
the fuel droplets? Toby
